Color filters are an accessibility feature of 📝Apple's iOS that support users with color blindness or other vision challenges by letting them differentiate between colors more easily, accessed through General > Accessibility > Accessibility Shortcut > Color Filters.
Once enabled via the accessibility shortcut, the device can be switched between full color and monochrome by triple-clicking the home or side button — a toggle designed for medical accessibility that 📝Feed Cutters have repurposed as a behavioral tool. Because vibrant color is one of the primary mechanisms interface designers use to make a screen compelling, switching a device to grayscale strips away that pull; feed cutters use color filters alongside tracking tools like 📝RescueTime and blocking tools like 📝Facebook Newsfeed Eradicator to make time on the device less immersive by design rather than willpower alone.
